Apprise Emoji Support Added

Related issue (if applicable): #649

Emoji support added! 👍

Emoji's simply translate entries like :smile: to 😄 and so-forth prior to the body or title being sent upstream.

The AppriseAsset holds the global flag of the usage for this new feature. It introduces a new variable called interpret_emojis which can be set to the following:

• None: Disabled by default, but grant URL over-rides (allow the Apprise URL to contain a ?emojis=yes . This is the default behaviour
• False: Emoji's can never be applied to the URLs; all emoji processing is disabled
• True: Emoji's are enabled by default in all cases. Users can however specify ?emojis=no on their URL to cause the processing of that notification to not handle emojis.

The CLI has also been updated to add a -j or --interpret-emojis flag. If this isn't specified then the underlining AppriseAsset takes the value of None (see above for it's definition). Otherwise it is set to True.

Translations are based on this link: https://github.com/ikatyang/emoji-cheat-sheet and at the time of doing this PR, i have not added them all yet.

Everything seems to work as it should. It's now just adding all of the emoji's into the emojis.py file.

....This is going to take some time to do... it's a LOT of data entry. If anyone wants to help out, that would be great! 🚀
